WINDOW DEVICE.

Specification of Letters Patent. 'Patented Sept. 10, 1918.

Application filed December 18, 1917. Serial No. 207,728.

To all whom it may concern: 7

Be it known that I, CHARLES L. OSBURN, citizen of the 'United "States,residing at Aberdeen, in the county of Brown and State of South Dakota,have invented certain new and useful Improvements in Window Devices, ofwhich the following is a specification.

This invention relates to window ventilators, and more particularly toventilators of that type which may be placed in a window opening orremoved therefrom at will.

One of the main objects of the invention is to provide a ventilator ofthe character stated of simple construction which may be produced atsmall cost.

A further object is to provide a ventilator which is adapted to containa liquid to be evaporated by the infiowing air, means being provided forcausing the air to flow over the surface of this liquid so as to becooled thereby.

Further objects will appear from the detailed description.

In the drawings:

Figure 1 is-a perspective back view of a ventilator constructed inaccordance with my invention.

Fig. 2 is a transverse-section.

The ventilator is formed from sheet metal of suitable gage beingprovided with the front wall 1, back wall 2, end wall 3, and top 1. Thefront wall 1 extends substantially half the height of the front of theventilator casing, and the upper edge portion thereof is turned downwardand outward at an angle to provide an inclined lip or flange The spacebetween this flange and the top wall of the casing forms theair-discharge opening of the ventilator through which the air flows intothe room to be ventilated. This opening is covered by a screen 7 of wireor other suitable fabric which is secured to the flange 5 and teavertical flange 8 formed at the inner edge of top 4 by bending theforward portion of this top up at right angles. The upper edge portionof screen 7 is turned down in back of this vertical flange and issecurely held between the same and a packing strip 9 of rubber or othersuitable material which is held by a U-clip or bead 10 secured to thetop 1. This bead acts to secure the screen in position and also servesto provide a resilient cushion member adapted to be engaged by the lowerrall of the win.

dow sash for securing the ventilator in posi t1on 1n the window openlng.

The back wall- 2 of the casing is of somewhat less height than frontwall 1 and is provided with a downwardly and outwardly directed flange11. The space between this flange and the top of the casing constitutesthe air inlet opening 12. A screen 13 is secured over this opening bybeing fastened to flange 11 at its lower edge and to the top 4 at itsupper edge. This ventilator is placed in the window opening so as toextend the full width thereof, being securely held in position byengagement of the lower rail of the window sash with the packing strip9. The air flows into opening 12 through the casing and out of opening 6into the room.

To cool this air which flows into the room I provide means whereby thecasing may be partially filled to a predetermined level with water, theinflowing air being caused to pass 7 over the surface of this water soas to cause evaporation thereof and thus cool the inflowing air. Forthis purpose I provide an overflow tube 1 1 secured through the backwall 2, and a filling opening 15 through the top 4. Water or othersuitable liquid is poured into the casing through this opening so as tofill the same to a level with the outlet opening of tube 14. This waterprovides a comparatively large surface over which the incoming air iscaused to flow by means of the downwardly and forwardly inclineddeflecting plate 16 which projects downwardly from the rearward edge oftop-4 and extends the full length of the casing, the lower edge of thisplate being in a plane slightly above the upper edge of back plate 2.The deflector causes the air entering through opening 12 to flowdownward onto and over the surface of the water in the lower partof thecasing so as to cause the evaporation thereof, this evaportion of thewater serving to cool and dampen the air preliminary to its entering theroom through screen 7. In addition, the deflecting plate acts to directall particles of dust and foreign matter which may be contained in theair flowing into the casing onto the surface of the water so as to becaught and retained thereby, the water thus acting to thoroughly cleanthe air as it flows through the casing.
